Special features
Basic
The 400 kA per phase surge capability provides maximum protection for critical loads, reducing unplanned downtime and extending the life of drives and controllers. This high-energy rating translates to fewer nuisance trips in environments with broader transient events, improving overall equipment effectiveness (OEE) and energy management. The 240 delta (4W+G) high-leg delta configuration ensures robust protection across all phases in specialized motor and drive systems, enabling safer commissioning and simpler wiring in complex AC networks. The NEMA 4X enclosure with an internal terminal block simplifies installation in washdown or outdoor environments, reducing field wiring errors and service time during retrofit projects. A 15-year warranty, extendable to 20 years with registration, supports total cost of ownership goals by lowering maintenance frequency and replacement cycles. Compliance features, including RoHS, CSA, and UL certifications, help meet procurement and regulatory requirements while easing supplier qualification and audits. Overall, this unit integrates smoothly with standardized panel layouts and offers reliable, long-term protection for industrial controls, pumps, and production lines.

FAQs
Start by ensuring the main power is off and follow standard lockout-tagout procedures. Mount the unit in a suitable space, align with the panel door and internal terminal block, and connect incoming conductors per the manufacturer wiring diagram. The internal terminal block simplifies field wiring, and the NEMA 4X enclosure supports outdoor or washdown environments. Verify clearances, torque settings, and perform a functional test after wiring to confirm surge protection operation.
400 kA per phase specifies the maximum surge current the device can safely absorb on each line during a transient event. This rating translates to higher resilience against large, short-duration surges common in industrial settings, reducing the likelihood of protecting-critical components from damage and minimizing downtime. It is particularly beneficial for systems with multiple motors, drives, and switching loads that generate substantial transient energy.
Yes. The device uses a NEMA 4X enclosure designed for rugged environments, including outdoor and washdown areas. The internal terminal block facilitates secure wiring in challenging spaces, while the enclosure protects against dust, water, and other contaminants. For installation, ensure the panel location meets temperature and ambient conditions specified by Eaton and ensure proper grounding and bonding for optimal performance.
The unit complies with RoHS and carries CSA standards, along with UL 1283 and UL 1449 certifications, reflecting safety, performance, and regulatory compliance. These certifications support reliable procurement, audits, and a smoother path through regulatory approvals for industrial installations and panel-build projects.
The SPM400240H1X carries a 15-year warranty from delivery, extendable to 20 years when registered with Eaton. This long-term coverage reduces maintenance costs, minimizes replacement cycles, and improves total cost of ownership for plant operators and electrical distributors by providing predictable protection against transient events over the product’s life cycle.
